After uninstalling all applications related to Microsoft Office 2007 Beta 2 Technical Refresh (B2TR), the following error prompts during the installation of Microsoft Office 2007 RTM.

===== Setup Errors =====

Setup is unable to proceed due to the following error(s):The 2007 Microsoft Office system does not support upgrading from a prerelease version of the 2007 Microsoft Office system. You must first uninstall any prerelease versions of the 2007 Microsoft Office system products and associated technologies.Correct the issue(s) listed above and re-run setup.

===== Resolution =====

*** These are for advanced users only. Take your own risk!*** You have been WARNED!

– Try to install Office 2007 RTM. If it prompts the same setup errors (of prerelease version), use Windows Installer CleanUp Utility to check whether any of the Office 2007 related products have not been installed, and try to remove the programs using {*** Add or Remove Programs ***} first.

– If the RTM setup still prompts the same setup errors, use {*** Windows Installer CleanUp Utility ***} to remove the related products. I have resolved my setup problem using the Windows Installer CleanUp Utility, and thus, do *not* need to proceed to the following step. [;)]
